hintHint:

The volume of a pyramid is given by 1 third cross times b a s e space a r e a space cross times space h e i g h t

The correct answer is: 317 units³


    Area of the base triangle is fraction numerator 1 over denominator 2 end fraction cross times b cross times h
    equals fraction numerator 1 over denominator 2 end fraction cross times 14 cross times 8
    = 56 units
    Volume of the pyramid = fraction numerator 1 over denominator 3 end fraction cross times 56 cross times 17
    = 317 cubic units
